zed-remote-server heavy CPU usage during compilation

[bjackman]

Summary

While I am compiling the linux kernel on a remote server, the zed-remote-server spins up 300 threads and uses 100% of a CPU.

Description

Sorry not sure what details to provide here, I suspect not much is needed beyond the reference to the linux kernel tree, I guess this is something to do with the build process and its .gitignore.

So I think the repro would be:

1. Clone that repo on a remote server
2. Open it via Zed remoting
3. Install build deps. On a Debian system this is something like build-essential bc python bison flex rsync . If you have Nix you can use nix develop github:bjackman/limmat-kernel-nix#kernel to get a shell with deps installed
4. In the kernel tree: make defconfig && make -sj100

While that's compiling you'lll see zed-remote-server hogging resources.

We made some changes that should improve this a bit in #40433, but likely more work remains. Thanks for the clear reproduction steps.
